first i thought:
"wow, all those patterns and nice colors cant be random &| luck, awesome !"
then i realized:
"wait, is that music in sync that i´m listening to ? it is ! AWESOME !"
then i found the vsync-versions and thought:
"wtf !?! the music is actually sounding really good and the patterns are beautiful when not that fast ! MEGA-AWESOME !"

i like the hypnotizing "i wont press ESC yet, just another pattern..."-feeling in the 3GHz-Version ( without vsync, really fast so to say ) the most tho !

This thing, as far as I could see it in dosbox (fortunatelly many cycles would do the trick) is already great. I might try it in my pentium laptop for more speed (time to utilize that USB floppy drive I bought, since I have dos here and I don't want to burn more CDs :).

There are so many different patterns and colours if you leave it running and a tiny tune that is nice and fits. The code is interesting and is documented and you can see there the many different values for different patterns with cool sounding names :)

rrola: thanks for the explanation. I had a quick attempt at recreating it but failed :)

Interesting that totally different techniques can give similar results. Last time I played with that feedback + blur + sharpen effect, I ended up with something that looked like a slowly mutating 2d platformer level even.
